PORTABLE GAS OR ELECTRIC LIGHT.

SPECIFCATION forming part of Letters Patent N o. 725,027, dated April 14, 1903.

Application filed May 28, 1902.

To a/ZZ whom it may concern.-

Be it known that l, JOSEPH E. BOHNER, a citizen Ot' the United States, and a. resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Portable Gas or Electric Lights, of which the following is a specification.

The invention relates to improvements in portable gas and electric lights; and it consists in the novel features and combinations of parts hereinafterdescribed, and particularly pointed out in the claims.

My invention has for its objects to simplify and lessen the expense of manufacturing the lights and to improve their structure by providing adequate means for avoiding in the case of gas-lamps all possibility of leakage and in the case of electric lamps all possibility of abrading or cutting the insulation on the circuitwires within the conduit-tube of the structure, my invention being adapted for both gas and electric lamps of the character usually called drop-lights.

the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation, partly broken awayand partly in central vertical section, of a portable lamp or drop-light constructed in accordance with and embodying the invention, the same being adapted for use in connection with either gas 'or electricity. Fig. 2 is an enlarged detached central vertical section of a portion of same. Fig. 3 is a sectional view of a customary form of button which will be applied to the lower end of the 'conduit-pipe of the lamp when the latter is to be used in connection with electricity. Fig. 4 is a like View of a customary form of fitting which will be applied to the lower end of the conduit-pipe Of the lamp when the latter is to be used in connection with gas.

Fig. 5 is a bottom view of a modified form of lamp embodying my invention. Fig. 6 is a vertical section of same on the dotted line 6 6 of Fig. 5, and Fig. 7 is an enlarged detached sectional View of a portion of the conduit-pipe and hub from the lamp shown in Figs. 5 and G.

Serial No. 109,301. (No model.)

In the drawings, referring to Figs. 1 to 4, inclusive, 10 designates a portable light or lamp comprising a suitable stand 11, the tubular column 12, the capital 13 ornamenting thetop of said column, the base 14 for the bottom of said column, and the interior conduit-pipe 15, Whose upper end will receive the burner-either gas or electric-and whose lower branch 16 curves outward within the solid base 14 and is open at its end through the side of said base to receive either gas or 17 being applied to said base 14 when electricity is to be used and the tting 18 being applied to said base when gas is to be employed, said fitting 1S being adapted to be connected with the usual flexible gas-tubing "employed for'drop-lights.

The conduit-pipe 15, with its branch 1G, is in one continuous integral piece of tubing, being wholly devoid of joints and couplings, as shown, and the branch 16 is formed by bending on a curved line the lower end of said pipe outward in a horizontal direction. Theinvention will be fully understood from The base 14 is cast directly on the pipe 15 and inoloses the contiguous portions of the branch 16 and lower end of the main body of said pipe, said base 14 being of solid metal and its vertical center being in line with the center of the vertical portion of the pipe 15. At its upper endthe base 14 is formed with the shoulder 19 to receive the lower end of the tube or shell 12 andwith the annular vertical iiange 20 to enter the lower end of said tube or shell 12 and maintainthe same concentrically with the vertical portion of the pipe 15.

The base 14 at its lower end is formed with the downwardly-extending hub 21 and horizontal annular shoulder 22, the latter being adapted to contact withthe upper surface of the stand 11, and the hub 21 havinga threaded hole 23 and being adapted to seat within a socket 24 of said stand, as shown in Fig. 1, where said hub will be firmly secured by the screw 25 passing through the base of said socket and entering said hole 21. The base 14 thus rigidly holds the pipe 15 and 'firmly maintains the lower end of the shell 12 and is itself dui-ably and firmly connected with the stand 11. The upper end ofthe shell 12 electric Wires, as may be desired, the button ICO is held, as usual, by the capital 13, which has a threaded aperture in engagement with the threaded upper end of the pipe 15.

The outer end of the branch 16 is threaded to receive either the button 17 or fitting 18, as may be required, and the upper end of the pipe 15 will receive the burner.

It is an important feature of the invention that the conduit-pipe 15 is in one integral piece and that the base 14 is cast thereon, since by reason thereof the pipe may not only be firmly secured but has throughout a smooth bore and is devoid of joints and is adapted for use in connection with either gas or electricity. The absence of joints in the pipe 15 not only lessens the expense of manufacture but avoids all danger of leakage of' gas which might otherwise take place at said joints; and the smooth regular bore of and absence of rough .surfaces and sharp angles in said pipe 15 render it not only entirely convenient to introduce electric wires into said pipe, but all danger of injuryto the insulation on said wires is overcome. I regard it of great importance that the pipe 15 should be in one continuous piece, devoid of sharp angles, and that the base 14 be cast directly thereon and form a means for enabling`the securing of said pipe to the stand 11. f

The invention is not confined in every instance to all the special details of construe tion shown in'Fig. 1, but is in part applicable to other forms of lamps` and in Figs`. 5, 6, and 7 I illustrate a modified -embodiment of my invention.

In Figs. 5, 6, 7 the conduit-pipe 30'is in one piece and has the base 3l cast upon it but this base 31 being concealed within the large flaring shell 32 is not given a specially-ornamental outline. The shell 32 rests upon the stand 33, and the latter is formed with the transverse bar 34, upon the center of which the hub 35 of the base 31 is secured by a screw 36, the said hub being provided with a th readed hole to receive said screw. The conduitpipe 30 of Figs. 5, 6, and 7 corresponds substantially with the conduit-pipe 15 of Fig. 1; but owing` to the special form of lamp presented in Figs. 5, 6, and 7 the horizontal branch of the pipe 30 is extended outwardv beyond the shell 32, so as to be exposed to receive a button 17 or gas-fitting 18. The base 31 firmly maintains and adds strength to the pipe 30 and affords adequate means for enabling the eectual securing of said pipe to the stand 33. The pipe 30 is, like the pipe 15, in one continuous piece, devoid of joints and sharp angles, and adapted for use in connection with either gas or electricity.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a portable light, the stand, the conl duit-pipe in one continuous piece comprising the vertical body portion and the branch 16 curving outward from the lower end thereof, the inclosing shell for said body portion, the cast base rigid on and encompassing the said conduit-pipe at the curved portion thereof connecting the lower end of said vertical body portion and said branch, and means for securing said base to said stand; substantially as set forth.

2. In a portable light, the stand, the conduit-pipe in one continuous piece comprising the vertical body portion and the branch 16 curving outward from the lower end thereof, the base rigid on and encompassing the said conduit-pipe at the curved portion thereof connecting the lower end of said vertical body portion and said branch, and the screw passing upward through said stand and entering said base, said base having a threaded hole to receive said screw; substantially as set forth.

3. In a portable light, the stand, and the shell 12, combined with the interior conduitpipe 15 in one continuous piece having its lower portion bent outward to form a branch, the cast base 14 rigid onsaid pipe at the bent part thereof and intermediate the said shell and stand, and means for securing said base to said stand; substantially as set forth.

4. In a portable light, the stand, and the she1l`12, combined with the interiorconduitpipe 15 in one continuous piece having its lower portion bent outward to form a branch, the cast base 14 rigid on said pipe at the bent part thereof and intermediate the said shell and stand, and means for securing said base to said stand, the upper end of said base 14 having the shoulder 19 and iiange 20 to engage the lower end of said shell; substantially as set forth.

5. In a portable light, the stand, and the shell 12, combined with the interior conduitpipe 15 in one continuous piece having its lower portion bent outward to form a branch, the cast base 14 rigid on said pipe at the bent part thereof and intermediate the said shell and stand, and means for,I securing said base to said stand, the lower end of said base having the depending hub, and the said stand being formed with the socket to receive said hub; substantially as set forth.
